Overview

some tools used in a wps process like to have a HOME environment and might even write into the HOME folder (config, cache, ...).

With this new feature the HOME can be set to the current tempdir of the process. This feature is disabled by default and can be activated with the sethomedir=true flag in the pywps server configuration.

You are already using this in Process._set_grass:
